Microsoft acknowledges about the Homtail iPad issues, “Unfortunately, we’ve seen some issues with using Hotmail on the new Apple iPad. Specifically, composing and replying to an email isn’t working for some of our users. Rest assured that we’re working with Apple to understand the issues, and we’ll fix them as quickly as possible. In the meantime, we have directed all iPad traffic to our mobile Hotmail website. Alternatively, you can set up the iPad email client to use POP to download your Hotmail,” writes Mike Schackwitz, Program Manager, Windows Live Hotmail team.
